SRT-heaters

Supported Applications

The Omega SRT Series consists of OMEGALUX® silicone rubber extruded heating tapes designed for temperature maintenance in applications requiring moisture and chemical resistance. These low-watt density electrical resistance heaters are constructed with finely stranded resistance wires fully insulated with braided fiberglass, knitted into a flat tape with fiberglass yarn, and encapsulated in a void-free silicone rubber sheath.

Operating Conditions & Performance

The SRT Series is rated for a maximum exposure temperature of 450°F (232°C). The series operates at a nominal watt density of 4.3 W/in² (0.007 mm) and features a dielectric strength in excess of 2000V. Standard configurations utilize 16 AWG high-temperature 600V silicone rubber insulated lead wires emerging from opposite ends into an integrally molded separable plug.

Key performance parameters include:

• Maximum Exposure Temperature: Up to 230°C (450°F)
• Nominal Watts per Square Inch: 4.3 W/in²
• Dielectric Strength: In excess of 2000V
• Media Compatibility: Moisture and Chemical Resistant

Configuration Options

The series offers a broad range of configurations defined by width, length, voltage, and lead exit orientation. Standard models are available in widths corresponding to ½ inch (1 cm), 1 inch (2.5 cm), and 2 inches (5 cm). Lengths vary from 0.6 m (2 ft) up to 6.1 m (20 ft).

Available options include:

• Voltage Options: Standard models are supplied at 120 V; a 240V version is available by changing the digit preceding the hyphen in the model number from "1" to "2." All 240V versions are supplied without plugs.
• Lead Configuration: Heaters with power leads exiting the same end of the tape are ordered by adding the suffix "LSE" to the model number (e.g., SRT051-060LSE).
• Plug Availability: Standard 120V models include an integrally molded separable plug. Models marked with an asterisk in ordering tables do not come with a plug.

Key Product Differences

The SRT Series model numbering follows the format SRT<series>-<model_number>, where the series digits indicate width and length. For example, models beginning with "05" denote ½ inch (1 cm) widths, while those starting with "10" or "20" correspond to wider tapes.

Specific variations include:

• SRT05x Series: ½ inch (1 cm) width options ranging from 2 ft to 12 ft lengths at 120V and 240V.
• SRT10x Series: 1 inch (2.5 cm) width options with power ratings up to 1045 Watts for the longest standard configurations.
• SRT20x Series: 2 inch (5 cm) width options, offering higher total wattage outputs such as 2090 Watts at 120V for a 6.1 m length.
